Strongly recommended, a similar VC++ interface design procedures, this interface has become a system standard, but also has a variety of window effects!

这是一个画板程序的一部分，教你如何调制颜色！(This is a drawing board as part of the program, teach you how to modulated color!)

说明：  恐龙窗口功能，本代码演示实现窗口的操作和特效(Dinosaur window function, the code window for presentation to achieve the operation and effects)

说明：  text moving on graph

说明：  一个用VC编成的计算器小程序模仿WINDOWS的计算器的格式(A calculator compiled with VC Mini Programs imitates the format of WINDOWS calculato)

本程序提供两种界面换肤方式,文件夹中实现的是加载皮肤文件实现界面换肤(This program offers two kinds of interface ways, is to load the skin file folder in realizing interface change skin )

说明：  当对话框窗口拖动变化时，相关控件Cedit的范围相应变化。(When the dialog box, drag the window changes, related to the scope of the corresponding control Cedit change.)

基于对话框的系统优化工具，有助于学习对话框设计( mfc program)

输入三点的三维坐标，求立体空间的圆心所在，使用了对话框架构，里面的算法函数可以提出来单独使用(importation of 3D coordinates for a three-dimensional space where the center of a circle, use the dialog box structure, function inside the algorithm can be made to use separate)
